Is it true that thermal energy is the energy of molecules in random motion which travels from warm to cooler bodies
Answer (2)
Answer:Yes, it is true that thermal energy is the energy of molecules in random motion that travels from warmer to cooler bodies. This phenomenon is governed by the fundamental principles of thermodynamics, specifically the second law which states that heat naturally flows from higher temperature regions to lower temperature regions until equilibrium is reached. The transfer of thermal energy occurs through three main mechanisms: conduction, convection, and radiation.Conduction involves the transfer of energy through direct contact between molecules, where particles with higher kinetic energy collide with slower-moving particles, transferring thermal energy in the process. Convection, on the other hand, occurs in fluids such as air or water, where heated molecules become less dense and rise, allowing cooler molecules to take their place, establishing a flow of thermal energy. Radiation is the transfer of heat through electromagnetic waves, allowing energy to propagate through a vacuum, such as from the Sun to Earth.
